From http://en.wikipedia.org/wiki/Database_model

A database model is a theory or specification describing how a
database is structured and used. Several such models have been
suggested.

Common models include:
* Hierarchical model
* Network model
* Relational model

IBM IMS on the mainframe is the best probably known hierarchical DB.
IDMS is an example of a network DB.

Hi,

In the Redbook Stored Procedures, Triggers, and User-Defined Functions on DB2 Universal Database for iSeries,

I read : Several years ago a survey pointed out that a significant percentage of iSeries server customers did not even know that all of their business data is stored in a relational database.

I am one of those customers, I guess. Can someone point out to me how is it that my database is relational? I use only DDS.

Thanks
